"2.4.3.1 DA-Converter" (Page 106)
Digital analog converter calibration at 4 mA
Trimming is carried out in 3 steps:
"2.4.3.1.1.1 Enable 4 mA fixed"
•
This menu command causes the pressure transmitter to output 4 mA
constant current.
"2.4.3.1.1.2 enter value"
•
This reads the indicated current value on a connected ammeter, and en-
ters it in the menu.
"2.4.3.1.1.3 perform zero-point calibration"
•
The pressure transmitter performs a calibration and uses this value to
correct the current offset.
